Hi, can someone please verify my answers to this question. Thanks heaps!!

Find all complex numbers w and z satisfying:

1/w + 1/z = 1/wz and 2wz - z^2 -1 = 0

- I got the answers z = 1/3 +(or)- (√2 / 3) i and w = 2/3 + (or) - (√2 / 3)i

Multiply both sides of by wz to get w+ z= 1. Then w= 1- z so the second equation becomes which the same as . Use the quadratic formula, or complete the square, to solve that for z
